1.) In the week starting December 4th tens of millions of people from over 180 countries will participate in the Hour of Code Challenge. 2.) The Hour of Code's purpose is to introduce the world of computer science to everyone. 3.) What would motivate me to learn computer programming or coding is the fun games I get to play.
